What equation in slope-intercept form represents the line that passes
through the points (3,-2) and (1, -3)?
Answer:
2y = x - 7
Step-by-step explanation:
The general equation of the line is;
y = mx + b
where m is the slope and b is the y-intercept
To get the slope, we use the slope formula
m = (y2-y1)/(x2-x1)
(x1, y1) = (3,-2)
(x2,y2) = (1,-3)
m = (-3+2)/(1-3) = -1/-2 = 1/2
So we have the equation as;
y = x/2 + b
Multiply through by 2
2y = x + 2b
To get the y-intercept value, we substitute any of the points
Let us use the first point
While 3 will go for x , -2 will go for y; thus we have;
2(-2) = 3 + 2b
-4 = 3 + 2b
2b = -4-3
2b = -7
b = -7/2
So the equation is;
2y = x -7

A shade of green paint is made by mixing blue paint and yellow paint in the ratio of 4 to 3. How many pints of blue paint and yellow paint are needed to make 21 pints of the green paint? A. 12 pints of blue paint and 3 pints of yellow paint B. 9 pints of blue paint and 12 pints of yellow paint C. 16 pints of blue paint and 9 pints of yellow paint D. 12 pints of blue paint and 9 pints of yellow paint
Answer:
D
Step-by-step explanation:
The sum of the ratios = 4 + 3 = 7
The ratio of blue paint to the total paint = 4/7
The ratio of yellow paint to the total paint = 3/7
Pints of blue paint needed to make 21 pints of the green paint = 4/7 x 21 = 12 pints
Pints of yellow paint needed to make 21 pints of the green paint = 3/7 x 21 = 9 pints

For the linear equation, find the product of 5 and the linear equation, and solve both equations for y. 2x + 7y = 11
Answer:
(a) [tex]10x + 35y = 55[/tex]
(b) [tex]y = \frac{11 - 2x}{7}[/tex]
Step-by-step explanation:
Given
[tex]2x + 7y = 11[/tex]
Solving (a): Multiply equation by 5.
Multiply both sides by 5
[tex]5 * (2x + 7y) = 11*5[/tex]
Open bracket
[tex]5 * 2x + 5 * 7y = 11*5[/tex]
[tex]10x + 35y = 55[/tex]
(b) Solve for y in [tex]10x + 35y = 55[/tex] and [tex]2x + 7y = 11[/tex]
[tex]10x + 35y = 55[/tex]
Subtract 10x from both sides
[tex]35y = 55 - 10x[/tex]
Divide both sides by 35
[tex]\frac{35y}{35} = \frac{55 - 10x}{35}[/tex]
[tex]y = \frac{55 - 10x}{35}[/tex]
Factorize the numerator:
[tex]y = \frac{5(11 - 2x)}{35}[/tex]
Express 35 as 7 * 5
[tex]y = \frac{5(11 - 2x)}{7 * 5}[/tex]
[tex]y = \frac{(11 - 2x)}{7}[/tex]
[tex]y = \frac{11 - 2x}{7}[/tex]
When [tex]2x + 7y = 11[/tex] is solved, the solution will be: [tex]y = \frac{11 - 2x}{7}[/tex]

The Martin’s want to buy a new computer. The regular price is $849. The store is offering a 20% discount and a sales tax of 6% is added after the discount. What is the total cost of the computer?
Answer: The total cost of computer would be $719.95
Step-by-step explanation:
I use proportions for these types of problems so we begin with a proportion!
20/100=x/849
100x=16980
x=169.80
Then, after finding how much the discount is, we would subtract it.
849-169.80=679.20
Next, we would find the tax amount with another proportion to find what 6 percent of 679.20 is.
6/100=x/679.20
100x=4075.2
x=40.75
Lastly, we would add the tax, $40.75, plus the total after the discount, $679.20!
Hope this helps! Good luck! (:
is 1 1/2 equal to 1 to 2? why or why not
Answer:
No
Step-by-step explanation:
1 to 2 is 1/2
Answer:
No. See below.
Step-by-step explanation:
I've never heard anyone say this out loud. However, on Brainly, it is always interpreted as 1 1/2 = 1.5. So it is 1 plus 1/2.
1 to 2 is a ratio. For every set of car keys I have 2 house keys.
1 to 2 can be written either as 1/2 or 1:2 depending on how touchy your instructor is.
So no. 1 1/2 is not the same as 1:2

One evening, a restaurant served a total of 5/6 of a loaf of wheat bread and 3/10 of a loaf of white bread. How many loaves were served in all?
Answer:
1 2/15 loaves
Step-by-step explanation:
In a restaurant:
Total Loaf of wheat bread = 5/6
Total Loaf is white bread = 3/10
The total number of loaves that were served in all =
Loaf of wheat bread + Loaf of white bread
= 5/6 + 3/10
Lowest Common Denominator = 30.
Hence:
= 25 + 9/30
= 34/30
= 1 4/30
= 1 2/15 loaves
The total number of loaves served in all = 1 2/15 loaves
The radius of the circle above is 34 mm. What is the circumference of the circle? (Use 7 = 3.14.)
what percent is 52.8 of 55? also how did u get itttt
Answer:
The answer is 96%.
Step-by-step explanation:
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 55 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 55, so we can write it down as 100%=55.
4. We know, that x% equals 52.8 of the output value, so we can write it down as x%=52.8.
5. Now we have two simple equations:
1) 100%=55
2) x%=52.8
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=55/52.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 52.8 is what percent of 55
100%/x%=55/52.8
(100/x)*x=(55/52.8)*x - we multiply both sides of the equation by x
100=1.0416666666667*x - we divide both sides of the equation by (1.0416666666667) to get x
100/1.0416666666667=x
96=x
x=96
now we have:
52.8 is 96% of 55

Write the equation to find the nth term in the arithmetic sequence. First term:-10 and common difference:2
Step by step
Answer:
2n - 12
Step-by-step explanation:
The nth term of an arithmetic progression is expressed as;
Tn = a+(n-1)d
a is the first term = -10
n is the number of terms
d is the common difference = 2
Substitute
Tn = -10 + (n-1)2
Tn = -10 + 2n-2
Tn = 2n -10-2
Tn = 2n - 12
Hence the nth term of the sequence is 2n - 12
